Most conversations about changing the world eventually degenerate into despair or, after a hands-in-the-air “well, anyway…” segue, they lapse into a conversation about something more practical or pressing. That’s because most discussions related to big change are about tactics rather than strategy at the scale of the question — and nothing’s more depressing than a tactical discussion when a strategic one is required. It creates the illusion of impossibility; makes us feel like we’re no match for the huge social challenges facing us. We start to doubt that they can actually be overcome.
